iphone - iOS GameCenter Matchmaker not working -


i’m trying make custom matchmakingview using matchmaker. code below used find match.

when run on 2 different devices different game center accounts, both match none connect match. stuck in while loop in infinity , never out. have missed something, need call connect match?

- (void) findmatch{ gkmatchrequest *request = [[gkmatchrequest alloc] init]; request.minplayers = 2; request.maxplayers = 2; request.playerstoinvite = nil; nslog(@"start searching!");  [matchmaker findmatchforrequest:request                withcompletionhandler:^(gkmatch *match, nserror *error)  {      if (error) {          // print error          nslog(@"%@", error.localizeddescription);      }      else if (match != nil)      {          curmatch = match;          curmatch.delegate = self;            nslog(@"expected: %i", match.expectedplayercount);           while (match.expectedplayercount != 0){              nslog(@"players: %i", curmatch.playerids.count);          }          nslog(@"start match!");      }  }];

you should not using while loop wait expectedplayercount reach 0, instead implement gkmatchdelegate method:

- (void)match:(gkmatch *)match player:(nsstring *)playerid didchangestate:(gkplayerconnectionstate)state {     if (!self.matchstarted && match.expectedplayercount == 0) {         self.matchstarted = yes;         //now should start match.     } }

keyboard - C++ GetAsyncKeyState alternative -

i using windows.h library's getasynckeystate function define key pushed on keyboard . here program returns int value of pushed key example. #include <iostream> #include <windows.h> using namespace std; int main (){ char i; for(i=8;i<190;i++){ if(getasynckeystate(i)== -32767){ cout<<int (i)<<endl; } } return 0; } but trying make opengl simple game , function appeared slow . there function not need cycle 180 times , if statement . thanks you're trying make opengl game, you're going use glfw. if that's case can away using glfwgetkey() such: if (glfwgetkey(glfw_key_up) == glfw_press) {...} if (glfwgetkey(glfw_key_down) == glfw_press) {...} that method nicely explained in tutorial 6 opengl-tutorial.org . should start first tutorial of beginners tutorials , later intermediate tutorials . if you're going make win32 window can listen wm_keydown or wm_keyup messages , virtua
